Did it a few years ago on the CBR6's and didn't rate it to be honest. If you want to find a perfect line round Donington, then it's great for that. I didn't learn any riding techniques or come away from it any quicker than I went there. You only get three sessions on track with brief classroom bits in between, and it's not nearly enough tracktime for the money. If you get paired with somebody who's either a lot faster or a lot slower than you, you'll be fed up of either getting left behind or held up as the instructor will go at the pace of the lead rider.
Most people would be better off booking a normal trackday and using whichever of the free instructors there best suit them. You'll learn more and they can cater the tuition to exactly what you want

If it's a first time on track, then great, as all the overtakes have to be by letting people by, so it's all very safe and civillised. If you've got half a clue what you're doing on a bike, just book a trackday.
